Douluo: Twelve Years in Seclusion, Then I Crush Tang Hao

[Fast leveling + beating up the Three + beating up Tang Hao + multiple heroines]

Cao Kun transmigrates to Douluo Dalu, becoming a six-year-old boy.

Adopted by Zhao Wuji, he joins Shrek Academy with him.

Cao Kun awakens a sign-in System.

From the start, he awakens two Martial Souls: a Body Martial Soul and the Chaos Bell Martial Soul!

After twelve years of secluded cultivation, he has reached level 99 and become a Limit Douluo.

Just as Tang Hao arrives to stand up for Tang San and teach Zhao Wuji a lesson, Cao Kun steps in without hesitation and punches the Clear Sky Hammer flying, easily subduing Tang Hao.

…

Tang Hao: How can you be this strong?

Cao Kun: I’m at Shrek Academy. Isn’t it only natural to be a little strong?
